Embodiment 1

[0040] Example 1 Dongnong 303 Potato Covering Grass Cultivation Method

[0041] 1. Overview

[0042] In late January, 200㎡ of special early-maturing variety Dongnong 303 potatoes were sown.

[0043] 2. Sowing

[0044] Choose a single seed potato with a weight of about 30g. Seed potatoes with a weight of more than 50g should be cut into pieces, and each piece must retain 1 to 2 healthy bud eyes. Soak the seeds with 50% carbendazim wettable powder 300 times solution for 3-5 minutes, take them out and stuff them for 6-8 hours, dry them before sowing.

[0045] 3. Fertilize the soil

[0046]When preparing the soil, apply 600kg of corroded manure, cover the seeds with 300kg of burnt marl, and spread 10kg of compound fertilizer without contacting the seed potatoes. The width of the furrow is 1.2m, and the width of the walkway between the furrows is 30cm. The sowing row is perpendicular to the length direction of the furrow, and 8 plants (holes) are sown in each row, the distanc...

Embodiment 2

[0053] Embodiment Two Kexin No. 4 Potato Grass Covering Cultivation Method

[0054] 1. Overview

[0055] In early February, the early-maturing variety Kexin No. 4 potatoes were sown, covering an area of ​​250 square meters.

[0056] 2. Sowing

[0057] Same as embodiment one.

[0058] 3. Fertilize the soil

[0059] Same as embodiment one.

[0060] 4. Mulch Weeds

[0061] Same as embodiment one.

[0062] 5. Thinning cultivation

[0063] Keep 2-3 branches for each plant (hole), and remove the excess. Other cultivation measures are omitted.

[0064] 6. Harvest

[0065] In late May, 591kg of potato tubers were harvested, and the yield per mu was 1576.8kg, which was 23.2% higher than that of conventional (ck1280kg); labor was saved by nearly half, and economic benefits were significant. If the rice field is covered with grass in the dry land, the yield per unit area (667㎡482kg) is less than one-third of that of the rice field.

Abstract

The invention discloses a grass mulching cultivation method for potato: the traditional potato mulching grass cultivation technology is realized in the rice field, the mulching grass is the straw, and the method is only realized for the rice rather than mountainous upland. The mulching grass method is realized in the dry land and the mulching grass is Chinese silvergrass sweet wormwood wild grass rather than straw; the method comprises the steps as follows: preparing land, digging holes, fertilizing, sowing and covering the grass; the grass mulching step is realized in two separated steps: the first time is the end of sowing operation, the covering thickness is 5-6cm; the second time is after budding, the covering thickness is 4-5cm; while sowing, arranging is arranged according to the broad row dense plant or broad-narrow row; no-tillage technology is implemented after budding, which saves most cultivation operations; while harvesting, the grass is pushed aside and the potato blocks are picked up. The method can improve the yield of the potato block by 23% to 36% and change the potato digging state into the potato picking state, save the labor force by about 50%, increase the soil fertility and have the remarkable economical benefit.

Description

technical field [0001] The invention belongs to a cultivation method of crops, in particular to covering cultivation of crops, in particular to a cultivation method of covering weeds when potatoes (Solanum tuberosum L) are sown in dry land. Background technique [0002] Potatoes belong to the family Solanaceae and are widely cultivated in my country. The growth and harvesting time is short, and it usually takes 60-70 days for early-maturing varieties to harvest after emergence. The tubers are rich in starch, resistant to storage and transportation, and can be used as staple food and vegetables. [0003] Potatoes are covered with straw when sowing, which is a way of crop cover cultivation, and it is a ground cover method. Crop mulching cultivation mainly has the following methods: sunshade net mulching, insect-proof net mulching, plastic film mulching, greenhouse mulching, straw mulching, and chaff mulching. Among them, the surface (surface) coverage includes plastic film ...
